I was diagnosed with Parkinson’s disease in 2020. Recently, I’ve been having problems with my eyesight. I find it difficult to focus when reading text; it becomes blurred. My eyes feel strained. Naturally, I have to make an effort to focus, and I feel I need more light than before. I’ve had high blood pressure for about five years, but my doctor has decided that I don’t need medical treatment. I’m currently taking 450 mg of levodopa, 90 mg of duloxetine, 50 mg of sertraline and 15 mg of mirtazapine. Could my vision be affected by Parkinson’s?

Yes, vision can be affected in various ways by Parkinson’s, but also, of course, by ageing. The first step when your focus and night vision deteriorate is to visit an optician and have your eyes tested; you may well need reading glasses, for example. It is also a good idea for those with glaucoma to have their eye pressure checked regularly, as levodopa can affect this. /Dag Nyholm
